We look at the division of 729156 by 20 
We want to figure out the number of times 729156 can be divided by 20.

Moving on to step 1:
20 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Let's proceed to step 2:
72 divided by 20 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 72 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 20

Step 3:
20 can be fit into 129 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 9 after subtracting 120 from 129.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Going ahead to step 4:
The number 20 fits into 91 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 364.0
If we take 80 away from 91, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 20

Moving on to step 5:
115 divided by 20 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3645.0
If we take 100 away from 115, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 20

Let's proceed to step 6:
When dividing 156 by 20, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 36457.0
Subtract 140 from 156 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
160 divided by 20 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 36457.8
The remainder is 0 after subtracting 160 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36457.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36457.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 36457.8 and a remainder of 0.0.
